Validatious 2.0 – Easy form validation with unobtrusive JavaScript
Validatious 2.0 allows you to do easy form validation with unobtrusive JavaScript. It’s standalone which means it requires no JavaScript library. However, if you’re already using one, Validatious can easily work with it, and even benefit from it. Validate forms with Plain Old Semantic HTML (yes, that’s POSH) and/or a simple JavaScript DSL: validate( “email”.is(“required”).andIsAn(“email”) ); or add custom validators with only a couple of lines of JavaScript.
